How To Proof Yeast

Unfamiliar with this baking technique? We're here to simplify it for you. Learn the best way to bloom yeast with this tip from Test Kitchen Specialist Pam Lolley.


This is the best way to bloom yeast. We like to use active dry yeast because it needs to be proofed, and proofing your yeast is the best way to find out if it's dead or alive. Always check the expiration date on the package. To proof, add your yeast to your warm water. The water should be between 100 and 110 degrees. If you don't have a thermometer, use your wrist to test the water temperature. If it feels very warm on your wrist, it's perfect for the yeast. Sprinkle the yeast and sugar on top of the water and stir. The sugar helps activate and feed the yeast. After a few minutes, your yeast should be bubbly like this. If your water was too hot or your yeast was old, your yeast mixture will look cloudy and flat like this, and you'll need to start over again. Check out Southern Living for more cooking tips.
